  • FIG. 21 is a front view schematically showing a prior art connector of this kind.
  • 100 and 101 designate the body and a card insertion port, respectively.
  • a required number of contacts 102 of contact piece members attached to the body 100 can be seen from the outside through the card insertion port 101. In other words, the contacts 102 always protrude into a card insertion space formed in the body 100.
  • FIG. 22 shows a card C such as an IC card which can be used in the connector of FIG. 21.
  • a required number of external contacts 112 are formed so as to have a predetermined pattern in an external contact forming region 110 on the surface of the card C.
  • the external contacts 112 of the card C are counter parts of the contacts 102 of the connector.
  • a connector in which a measure for preventing scratches from being formed on a card is proposed by, for example, Japanese Utility-model Publication No. 7-33401.
  • a connector described in the publication comprises the body and a slider housed in the body.
  • a mechanism for displacing the slider which is pushed by the tip end of the card in a direction toward contacts of contact piece members disposed inside the body is interposed between the body and the slider.
  • the contacts of the contact piece members are not in contact with the surface of the card, so that scratches are not formed on the surface of the card.
  • the publication describes a measure for holding the card inserted into the body in position.
  • the measures for preventing scratches from being formed on the surface of the card, and for holding the card inserted into the body in position which are described in the publication are configured by interposing a member which is other than the slider, between the slider and the body. These measures increase the number of components and also the complexity of the structure. Therefore, these measures impede reduction of the production cost of a connector, etc.
  • the present invention has been conducted in view of the above-mentioned circumstances.
  • the connector of the present invention which attains the abovementioned objects comprises:
  • a slider which is held by the body so as to be slidable in card inserting and ejecting directions between an initial position on the side of a rear portion of the body and a pushed-in position on the side of a front portion of the body;
  • elastically urging means for always elastically urging the slider in the card ejecting direction
  • a contact piece member which is held by the body and which comprises a contact which uses an external contact on a surface of the card as a counter part, the contact piece member having elasticity for always urging the contact in a direction along which the contact protrudes into the card insertion space;
  • a contact position regulating mechanism which is interposed between the contact piece member and the slider, which, when the slider is at the initial position, retracts the contact of the contact piece member to the outside of the card insertion space against the elasticity of the contact piece member, and which, as the slider slides from the initial position to the pushed-in position, allows the contact to protrude into the card insertion space by the elasticity of the contact piece member.
  • the engaging portion is pushed and moved by the operation of inserting a card, and the slider comprising the engaging portion is caused to slide from the initial position to the pushed-in position.
  • the slider is caused to slide from the pushed-in position to the initial position by the elastically urging force of the elastically urging means.
  • the contact of the contact piece member is retracted to the outside of the card insertion space by the contact position regulating mechanism.
  • the contact of the contact piece member protrudes into the card insertion space. After the contact protrudes into the card insertion space, the card is inserted into or ejected from the card insertion space while rubbing against the contact.
  • the contact rubs against only the surface of the external contact forming region of the card.
  • the surface other than the external contact forming region of the card which is inserted into or ejected from the card insertion space will not be scratched.
  • the mechanism for preventing the surface of the card from rubbing against the contact of the contact piece member is provided not in another member, but in the slider, so that it is unnecessary to use any additional component for the mechanism.
  • the number of components can be reduced, and it is possible to provide a connector at a low production cost.
  • Another connector according to the present invention relates to the shape of the contact of the contact piece member and the structure of the contact position regulating mechanism. That is, in the connector according to the present invention, the contact piece member elongates from an end portion of the body in the card inserting direction along the card ejecting direction, an end portion of the contact piece member is bent and formed as an angled portion, a top portion of the angled portion is formed as a contact, and
  • the contact position regulating mechanism comprises: a projecting piece which is cut and raised to protrude in the card ejecting direction from a slope portion positioned closer to a basal portion of the contact piece member than the top portion of the angled portion; a pressing face which is formed on the slider, and which, when the slider is at the initial position, overlaps the projecting piece to prevent the projecting piece from being displaced in a direction toward the card insertion space by the elasticity of the contact piece member; and an opening which is formed in a portion adjacent to the pressing face in the slider, and which allows the projecting piece to be displaced in the direction toward the card insertion space as the slider slides from the initial position to the pushed-in position.
  • the pressing face of the slider overlaps the projecting piece of the contact piece member, thereby blocking the projecting piece from being displaced in the direction toward the card insertion space.
  • the contact does not protrude into the card insertion space, and the card is inserted into or ejected from the card insertion space while the surface of the card does not rub against the contact.
  • the projecting piece of the contact piece member is allowed to be displaced in the direction toward the card insertion space through the opening of the slider.
  • the card After the contact protrudes into the card insertion space, therefore, the card is inserted into the card insertion space or ejected from the card insertion space while rubbing against the contact. Accordingly, in the same manner as the case described above, if a timing when the contact protrudes into the card insertion space, and when the external contact forming region of the card opposes the contact in the middle of the insertion or ejection of the card to or from the card insertion space are appropriately determined, the contact rubs against only the surface of the external contact forming region of the card.
  • the pressing face of the slider still overlaps the projecting piece.
  • the contact rubs against only the surface of the external contact forming region of the card.
  • the projecting piece moves closer to the card insertion space through the opening of the slider, so that the contact comes into contact with the external contact forming region.
  • the contact rubs against only the surface of the external contact forming region of the card.
  • the slider comprises an arm which has elasticity, in which a basal portion is cantilevered by the slider, and which is elongated in the card inserting direction, a tip end portion of the arm has a head portion which protrudes in the card insertion space when the slider is at the initial position, an upward slope face which is formed in the head portion functions as the engaging portion which is to be engaged with the tip end of the card, an engagement pawl is disposed in the head portion, and
  • the body comprises: a guide face on which, when the slider is pushed and moved by the card from the initial position to the pushed-in position, the engagement pawl slides, thereby preventing the head portion from being pressed down by the card; an opening which is disposed adjacent to the guide face, and in which, when the slider reaches the pushed-in position, the engagement pawl of the head portion which is pressed down by the card against the elasticity of the arm falls in the opening, thereby allowing the tip end of the card to ride over the head portion; and an engaging portion which is to engage with the engagement pawl which is in the opening, in the card ejecting direction.
  • the connector when the slider is pushed-in and moved from the initial position to the pushed-in position by the card, the engagement pawl of the head portion which is disposed in the slider via the arm is engaged with the engagement portion of the body, and the slider is locked in that position. Even if the slider is elastically urged in the card ejecting direction, therefore, the slider will not return to the initial position due to the elastic urging force. Thus, the card is kept to be inserted into the card insertion space. When, in a condition where the slider is locked as described above, the card which is inserted into the card insertion space is pulled and moved in the card ejecting direction, the tip end of the card is retracted from the space above the head portion.
  • the head portion is restored to the original position due to the elasticity of the arm.
  • the engagement pawl is released from the engaging portion and the lock is canceled.
  • the slider is then returned to the initial position by the force which elastically urges the slider in the card ejecting direction.
